--memory-reservation=number[unit]

Memory soft limit. A unit can be b (bytes), k (kibibytes), m (mebibytes), or g (gibibytes).

After setting memory reservation, when the system detects memory contention or low memory, containers are forced to restrict their consumption to their reservation. So always set the value below --memory, otherwise the hard limit takes precedence. By default, memory reservation is the same as memory limit.

This option is not supported on cgroups V1 rootless systems.
